As Lee Jay states the camera need not match (file type is more important though -jpeg/raw) so I would use the D90 sensor for the D300s. I haven't used these profiles as I don't have the lens and would suggest you try them all and find the best one for you.

None of the user-supplied profiles for that lens are particularly complete. The most complete is the one for the D3 by George Purvis, which includes four measurements -- all at ƒ/11. He varied the focal length and focus distance.

The others for the D90 are all from Spike, and each has only one measurement.
